Title: Image information storage device and image processor provided with the same
Inventor: SHIMIZU YASUMITSU
IPC: G06F3/06
Filed: 2000-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent a recording medium from being erroneously transferred and wastefully consumed without interruption of transmission even if such operations as opening a tray and turning off the power supply of the recorder are carried out during operation of transmitting image information between memory in an image processor and an external storage device having attachable and detachable storage medium. SOLUTION: When transmission is accepted and a transmission button is pressed after insertion of a recording medium has been confirmed, a tray-lock command is sent to a CD drive of an external storage device (S155). When the tray is locked, transmission processing is started and completed, and the tray is released from the locking (S157). A command for switching off the power supply to the storage device is also rejected during transmission. In a write-limit type recording medium such as CD-R, CD-R/W, or the like, mis-writing is prevented by a tray locking means and a means for disabling OFF- operation of the power supply key, and thus the recording medium is efficiently used.
